GeoBrakes stocks complete parking brake shoe kits confirmed to fit the Lexus Rx300 drum-in-hat rear parking brake system, combining OEM-grade parking brake shoes matched to the Rx300 drum diameter with the return springs, shoe strut, adjusting screw assembly, and retaining clips needed for a correct, fully functional parking brake service on your Lexus Rx300. Replacing shoes without the hardware is the leading cause of parking brake failure after service on the Rx300 in American conditions.
A parking brake shoe kit for the Lexus Rx300 restores complete parking brake function, not just the friction lining. The most common reason a freshly serviced Rx300 parking brake fails to hold on a hill is not worn shoes: it is a seized adjuster that prevents the shoe-to-drum clearance from being correctly set after installation on your Lexus Rx300. In the enclosed drum-in-hat cavity of the Rx300, road salt and meltwater concentrate corrosion on the adjuster threads, the return springs, and the strut. A kit that includes every hardware component alongside the shoes is the only way to guarantee the Lexus Rx300 parking brake performs correctly after service.
The kit for your Lexus Rx300 includes parking brake shoes with OEM-grade friction lining at the correct arc length and lining width for the Rx300 drum-in-hat diameter, return springs that retract both shoes cleanly after the Rx300 parking brake is released, hold-down hardware with springs and pins that locate the shoes while permitting actuation on your Lexus Rx300, the parking brake strut connecting both shoes through the Rx300 mechanism, the adjusting screw assembly setting correct shoe-to-drum clearance for reliable holding force on your Lexus Rx300, and retaining clips and washers securing the strut and adjuster in correct operating position on the Rx300.
The parking brake shoe adjuster on the Lexus Rx300 sets the gap between the shoes and the inner drum surface of the Rx300 rotor hat. In American winters, the drum-in-hat cavity of the Rx300 traps road salt and moisture. The adjuster threads on your Lexus Rx300 corrode and seize, sometimes within a single winter season. A seized adjuster on the Rx300 produces a parking brake that either drags against the drum when released or fails to hold the Lexus Rx300 on a slope when engaged.
Parking brake shoe kits for the Lexus Rx300 are among the most vehicle-specific brake components in the catalogue. The shoe arc length, lining width, spring rates, strut length, and adjuster thread specification for the Rx300 are all determined by the specific drum-in-hat diameter of the Lexus Rx300 rotor. Every kit in the GeoBrakes catalogue is assembled for the Lexus Rx300 exact year and model, with zinc-plated or coated hardware components to resist the concentrated corrosion inside the Rx300 drum-in-hat cavity.
How do I know if my Lexus Rx300 uses parking brake shoes?
Lexus Rx300 vehicles with four-wheel disc brakes often use a drum-in-hat parking brake requiring separate shoes. Some Rx300 variants instead use a caliper-actuated parking brake. Use the GeoBrakes vehicle selector to confirm your Lexus Rx300 parking brake type and find the correct kit.
My Lexus Rx300 parking brake light stays on after I release it, do the shoes need replacing?
A warning light that stays on after full release on the Lexus Rx300 can indicate worn shoes, a faulty sensor, low brake fluid, or a stretched cable on the Rx300. If the Lexus Rx300 fails to hold on a slope, a shoe kit replacement combined with cable and adjuster inspection is the recommended starting point for your Rx300.
Can I adjust the parking brake on my Lexus Rx300 after installing a shoe kit without replacing the cable?
Yes, if the Rx300 cable is in good condition and within its adjustment range. After correct shoe installation and adjuster setting on the Lexus Rx300, adjust the cable until the brake holds firmly within three to five clicks of Rx300 lever travel.
